CONSERVATIVES BACKED BY KOHL TOP EAST GERMAN VOTE SOLIDLY BUT APPEAR TO NEED COALITION
LEAD: A group of conservative parties, led by the Christian Democrats and actively supported by Chancellor Helmut Kohl of West Germany, scored a surprising victory on Sunday in the first free election in East Germany. The eastern Germans had not freely cast their ballots since Hitler abolished the Weimar Republic after coming to power in 1933.
